SITUATION: You want a sauna outdoors, or if indoors you'd rather not endure construction in a spare room, or you may want a sauna kit you can relocate, or your sauna location is in the woods. DIY assembly time: 1/2 day, excluding base prep work

Sauna kit starts as a wooden frame over the base

The panels are screwed together which form the sauna room walls. Each panel is 6'4"H x 4"D x Width is flexible and depends on your site's needs, but usually 2' or more.

Add the sauna door – which is part of a wall panel

Pre-built ceilng panels completely enclose the sauna, so interior height is 6'4", but can be made taller. If outdoors, add the sauna roof.

Next, you'll need to wire for your sauna heater. A conduit planned through the panel makes it easy to push your wire through. Or your electrician can just drill a hole. Mount or set your heater. Add your benches and you're ready to take a sauna.

Indoor prefab sauna kits are usually placed in a larger room, basement, cabin or sometimes under an outside shelter. This sauna kit can be erected indoors or outdoors, and can be taken down and moved (in about a half-day). If you're wanting a stand-alone outdoor sauna, then we include an sauna roof kit.

Outdoor prefab sauna kits should be erected on a suitable base, such as, pressure-treated wood, cement, pavers or tile. If you're building this kit indoors, then any non-permeable base will work. Tile or vinyl are common. Or if you have an outdoor shelter, then you're fine with just the ceiling panels. Sauna roof kits do have space for more insulation, if desired. See how to build a prefab sauna kit outdoors.

Many picture an outdoor sauna experience as a healthy sweat next to a wood-fired sauna heater followed by an invigorating cold plunge in the lake. If you picture'd that too, then the outdoor prefab modular sauna kit is the best fit for a traditional sauna experience.

DIY Precut Home Sauna Kit — How to Build: Converts a framed room into an indoor sauna

To order this kit, you'd need to measure your room's walls. Download the Precut Sauna Field Measurement Form (PDF) to measure your new sauna room. Keep in mind saunas do NOT need a high ceiling. In fact, a lower ceiling keeps your heating costs down. A range of about 6'8" to 7'4" is a good ceiling height for an indoor sauna.
